Zayo Group (news, filings) isn't wasting time putting its newly national footprint to work. Less than six months after closing the AboveNet deal closed and a year since picking up 360Networks' western fiber infrastructure, they're putting 100G gear on the combined assets.
100G wavelengths are already operational on some routes, with 24 major markets planned for the initial implementation described by the map to the left. Interestingly, they chose to light the northern tier route with 100G, giving them a diverse route from the usual Seattle-Denver-Chicago pathway, and also the Chicago-New Orleans route as well.
They'll be offering 100G wavelengths to their customers, but I'll bet that continuing to scale the AboveNet IP backbone was a big part of the decision to take the plunge now. No word on the gear being used, yet anyway.
The second half of 2012 has seen a lot of 100G deployment announcements in the US. A few months back, it was XO announcing a buildout, then CenturyLink, Teliasonera, and now Zayo. In this piece a few months back, Level 3 detailed how it has rolled out 100G in the past, but that the market was not yet mature for the economics to work out for widescale adoption. It seems that the situation may be starting to evolve rapidly.
Zayo has bought six companies in the past 12 months, or at least it will when it closes the pending acquisition of First Communications. They have a few holes left to fill in their metro coverage, such as Florida, and their intercity backbone is a a few dark fiber IRUs in parts of the country, but it's been amazing to watch them piece together the extensive assets they now operate in just five years.
